40341af448 fs: returns EBADF on negative file descriptor (#1391) 
This changes file descriptors from uint32 to int32 and the
corresponding file table to reject negative values. This ensures
invalid values aren't mistaken for very large descriptor entries, which
can use a lot of memory as the table implementation isn't designed to
be sparse.

ea336061c2 wasi: introduce platform.Select and use it for poll_oneoff (#1346)

Details 
The PR introduces the `platform.Select()` API, wrapping `select(2)` on POSIX and emulated in some cases on Windows. RATIONALE.md contains a full explanation of the approach followed in `poll_oneoff` to handle Stdin and the other types of file descriptors, and the clock subscriptions.

It also introduces an abstraction (`StdioFilePoller`) to allow the simulation of different scenarios (waiting for input, input ready, timeout expired, etc.) when unit-testing interactive input.

This closes #1317.

d63813a830 fs: stat and cache mode for stdio devices (#1295) 
Ensure that stdio device modes are consistent with the given
file descriptors by stat'ing, instead of returning mocks.

* Use `Stat()` on `poll_oneoff()` too, instead of `IsTerminal()`,
thus avoiding a useless syscall.

* Delete leftover type decl `fileModeStat`.

* Remove IsPlatform()

* Propagate error when Stat() fails

36bf277534 sysfs: requires all methods to return syscall.Errno (#1264) 
This forces all syscall functions, notably filesystem, to return numeric
codes as opposed to mapping in two different areas. The result of this
change is better consolidation in call sites of `sysfs.FS`, while
further refactoring is needed to address consolidation of file errors.

046af4356e wasi: removes constraint around closing a pre-open, and temporarily skips interesting_paths (#1265) 
wasi-testsuite changed its mind on pre-open WebAssembly/wasi-testsuite#66

they also now explicitly forbid paths being passed in with a leading slash. Even when the config bug on WebAssembly/wasi-testsuite#67 is finished, this requires discussion if we want to EPERM on that.

c46a6eb4ae sysfs: return st instead of accepting it (#1261) 
This returns stat as a value instead of a pointer param. This is both
more efficient and faster. It is also more efficient than returning a
pointer to a stat.
